Error Installing SiteBuilder (Again?)

When I try installing SiteBuilder using SSH, an error appear as below: error: Failed dependencies: php >= 4.3 is needed by Sitebuilder-1.1.1-rhel3.build050117.10 php-mysql is needed by Sitebuilder-1.1.1-rhel3.build050117.10

And then I checked my server system info, the results: ========================= - Checking for PHP version: PHP version: 4.3.10 Version ok PHP safe mode off

- Checking for MySql version: MySQL version: 3.23.49 Version ok

- Checking for ImageMagick: ImageMagick not found in location. (Download CGI script to test ImageMagick without knowing path)

- Checking for GD: GD Version: bundled (2.0.28 compatible) Version Ok

PNG Support is enabled JPEG Support is enabled GIF Support is enabled WBMP Support is enabled Checking for GD 2.x: GD 2.x found

- Trying to create image via GD 2.x: For atleast next 10 seconds, don't press anything, click retry when prompted to do so File creation was successful ================================= Anyone how to fix them out?
